With compassion and curiosity, we have life with a purpose. We recognize that we have abilities like senses to accumulate data and memories to store that data. In our minds we can reason, analyze and conclude the data into not only simple understandings but also into complex understandings that continue on into comprehensive understandings. That comes from our curiosity. What comes form our compassion is our need for connecting with each other. We are not automatons, we are biological beings in need of an understanding of our emotions and related behaviors. Our species nurtures us from our infancy to our maturity in most cases. We are bound to each other in ways that even extend out to the "lesser species". We have a "heart" within us that demands our attention to each other.
For me to make up or need a symbol of righteousness to know that I am worthy as a human being is ludicrous. I get my bearings from my human nature, my compassion and my curiosity. Now you may wonder how I deal with our lesser natures of harm and derangement. Simple, they come about due to a lack of both compassion and/or curiosity. Much like emptiness is filled like a vacuum with whatever is available if it is not already filled with compassion and curiosity. My compassion and my curiosity are my fulfillment. They serve as my principles for living as a human being worthy of any moral or ethical equivalent.
